C_DBADM_2404 Exam Dumps : SAP Certified Associate - Database Administrator - SAP HANA

One of the backup options provided by the SAP HANA database is:

• Data snapshots: This method captures the state of the database at a particular point in time, facilitating quick backups that do not significantly impact database performance.

References=Data snapshots are described in SAP HANA documentation as an effective way to quickly backup the database without the overhead of traditional full backups.

Backup and Recovery

You can resume the failed recovery of your productive SAP HANA tenant database in the following situations:

• An aborted recovery of a delta data backup: Resuming from a delta backup is possible because these backups capture changes since the last full or another delta backup, allowing the recovery process to continue from the last successful point.
• An aborted recovery of a log backup: Log backups contain all the transactions since the last log or data backup. If the recovery from these backups is interrupted, it can be resumed because the log contains all necessary information to bring the database to a consistent state up to the point of failure.

References=SAP HANA backup and recovery documentation explains the mechanisms and capabilities of the database's recovery features, including scenarios where recovery processes can be resumed after interruption.

Backup and Recovery

Savepoints in SAP HANA are triggered by:B. By issuing a transactional commit, which initiates a savepoint to ensure that all committed transactions are durably written to the disk.C. By a database soft shutdown, during which SAP HANA ensures that all changes are safely written to the disk in the form of a final savepoint to prevent any data loss.Savepoints are not directly triggered by performing a delta merge or a database backup; these processes may coincide with savepoints for consistency but do not inherently cause them.References= SAP HANA administration guide detailing how transactional data management is handled, including the automatic triggering of savepoints at specific operations like shutdowns and commits.
